So I installed the official version of Opera named "opera-stable" in the Ubuntu Software Center.
- When I run it from launcher, it launches twice and displays a message (Translated to English by myself, may not be perfect):
Cannot read user configuration files. Some features may not be available and any changes performed this session will not be saved. (Print Screen Image)
- When I run it from terminal, it throws these errors:
[1226/165646:ERROR:desktop_window_tree_host_x11.cc(889)] Not implemented reached in virtual void views::DesktopWindowTreeHostX11::InitModalType(ui::ModalType) [1226/165646:ERROR:download_history_importer.cc(50)] Failed to read a tag or its data. [1226/165646:ERROR:migration_assistant.cc(87)] Could not open file: wand.dat [1226/165646:ERROR:extensions_importer.cc(58)] Reading widgets.dat failed
- Running it with the "sudo" command works perfectly well, and saves all user settings. Though from what I read so far, having to run a browser with sudo is not a good thing.
Now, I'm a newbie, but I followed this which recommends:
sudo chown -R group_name.user_name ~/.opera
and indeed I seem to be the owner of all the folders and subfolders that opera uses (I can't remember the command I used to check that) but it still doesn't work.
I also tried loads of other things like updating, upgrading, apt-mark hold command, reinstalling opera (both using the software center and manually unpacking .deb file) and maybe something more. As I said, I'm a newbie, I only use Ubuntu for 2 days, I just want to get Opera up and running properly, but I spent those 2 days looking for an answer.
Here's a screenshot of .opera's permissions. Sorry for the language. I should switch to English.
